Just you, StepMommy and Your StepSister have gone away on holiday to spend some quality time together. With your StepSister resting in her bedroom it's just you and StepMommy relaxing by the pool. You've never properly seen her body before but she looks proper MILFY in that bikini, the top is really low and is leaving very little to the imagination. She rubs in her sunscreen and comes in close to ask you if it's rubbed in - seeing her tits up close like that being squeezed by her bikini top gives a very taboo erection. You try and hide it, it's kind of weird to get a boner over your StepMother. But she's your StepMom, and nobody can read you better than her. To your surprise she isn't angry that you've got a boner over her, infact she is flattered. She hates the thought of her precious boy being uncomfortable and blue balled while he is meant to be having the time of his life on holiday, and offers to fix your erection. You guys will have to be quiet though - your StepSister is in the room next door and she can never find out about this very taboo act! More so because she doesn't want your StepSister to start thinking that taboo relationships are acceptable - StepMommy wants you all to herself! That silly little bitch doesn't deserve a man like you.
Just as you are about to cum inside of StepMommy, she tells you she isn't on any protection. StepMommy doesn't care though, there's nothing she wants more than to feel your forbidden seed inside of her cunt. After all, the cherry ontop of this taboo filth sundae would be to get your StepMommy pregnant.
